Front 1

Adolph (2005)

Back 1

9000 steps per day

Front 2

Von hofsten and Ronquist (1988)

Back 2

Anticipory reaches. incorporates vision with motor plans.

at 4-5 months.

are these apparent 'reflexes' perhaps meaningful actions?

Front 3

Vollis and McFadgen (2005)

Back 3

by 10 years old, individuals are walking with the same ability as adults

Front 4

Thelen (1981, 1983)

Back 4

Stepping reflex disapears after one year, but it continues if the babies are put on their back.

1983 - if thin babies put on weight they stop stepping. if fat babies are put in water they start stepping. Shows the effect of biomechanics.

Front 5

Fantz (1961)

Back 5

Using forced choice preferential looking - showed that babies of only one week old showed preferences and therefore are sensitive to visual form.

Front 6

Slater, morrison and rose (1983)

Back 6

using habituation, found that a infant could actually discriminate after a few days. builds on evidence by fantz (1961)

Front 7

Cohen and Younger (1983)

Back 7

Age differences in when infants could discriminate orientations and angels.

orientations - 1.5 months
angels - 3.5 months

Front 8

Slater (1991)

Back 8

disconfirmed cohen and younger (1983) finding that newborns could discriminate angels and orientations.

perhaps this relates to them having the ability from birth but only learning to use it in the following months due to experience!

Front 9

Decasper and fifer (1980)

Back 9

Infants show preference for mothers voice 3 days after birth but no preference for fathers voice.

Front 10

Decasper and prescott (1984)

Back 10

suggested that this is due to learning in utero.
